List of disc compatible kids frames (<=24" wheel)

I'd like to compile a list of the known [rear] disc compatible kids frames 24" wheel size or smaller. So if you know of some, please help me by posting the frames below, I'll try to keep the thread updated if we end up with more than a few. Thanks for the help!

My son is currently riding a 20" wheeled Gary Fisher Precaliber that has disc brake mounts, but I have XT Vee brakes on it.
I recently got a GF Tyro (not sure what year) with 24" wheels and a cheesy steel frame that also has disc brake mounts, but now that I have the bike home and I see how heavy the frame is, I think it may not be worth building up.

renewing this conversation and does anyone have a disc frame available as frame only? Looking to build my daughter a 24 inch after I built her 20 inch 2 years ago and I'm looking to go full custom this time.
